Well I didn't do it on a TTA but on a national and it took me 3 days of after work hours to complete with everything back in its place. which was a total of about 7-8 hours. This was also my first time soldering anything and doing wiring of this caliber.
You will be extremely happy with it, I am now running 22#'s with zero knock
hey I've spent enough time on my back the past few years pulling trannies so if you want to come take the car and give it back with a fresh trans and an alky kit installed the key's will be here waiting for you.
